I have 4.88 gears in my 83, which had a 22r, with 35" tires. It had good acceleration until about 45mph then it was a dog. Also, once you start going up hills its all over, the speed drops quickly. If I did it again I would go with 5.29's. It was that way at least until I finished my 3RZ swap, now I have no problems with power.
